Prime rounding error in new OC? - Page 2

post #11 of 43
Thread Starter 
Hi Fishhawk, Ive been trying to get ahold of that cooler here in UK cant get one, also the 920 is unobtainable. Ive just seen this thogh dear but there you go, http://www.ebuyer.com/product/240796 I could buy that and have it here in the morning haha...

Id be worried incase it wont go in top of my Phantom case under the two 200mm fans I have without the ram being in the way, there are two brackets supplied with case so i suppose it must fit there, are all those double size rads universal size/fitting? I dont want to lay out £120 and have ram in the way lol.

Thanks for the post smile.gif

Hello again-ya i preodered my antec 620 strate from antec-69 U.S straight up no shipping,even got a free antec tshirt with it.And yes the bigger one i guess is not due out for quite awhile yet. And sorry-i wish i could help you more on how that rad your looking at will fit-but all i can say is take out a tape measure if your worried about the ram issue. As far as brakets-they should work.
P.S. Almost bought the case you have for my new build-was a coin toss between that one and the inwin dragon rider i did buy. They both ROCK!!

One thing i did with my antec 620-is i had it pushing air out the back of my case and it worked good-than after awhile i installed it in the top of my case-it dropped my temps by 2c on my cpu. Too me it was worth the move.

This level/type of error can be many things:
CPU Unstable Clock or Low Voltage
Memory Fault
Memory without enough Voltage
IMC voltage too low.
Memory Timings.

CPU-NB voltage is the IMC voltage.

I am always assuming when I read threads that stability at stock was already determined, and that the memory did indeed pass MemTest86. So while I didn't mention it, it is certainly a possibility.

The reason you test and stabilize each OC individually is why you don't have to juggle all these voltages trying to troubleshoot.

If the CPU is stable at 4 GHz, and you raise CPU-NB speeds up which no longer makes you stable. The culprit would be the CPU-NB.

When you have an OC on the CPU, the Memory clocks, the IMC, and voltages adjusted on all three. You have 6 possible avenues to troubleshoot, so 6 variables. Not the best approach.

That doesn't include the dozen or so memory timing options, which if you go to low, no voltage in the world can make you stable, and it will drive you nuts trying to figure it out.


Cooling Solutions:
I believe the best out of the box (thermal paste, heatsink, and stock fans) is still the NH-D14 Noctua. Its a high quality Austrian heatsink with about a gillion awards. Its very huge though.

That CoolIT I have not seen reviews, but its predecessor did fairly decent. The H70 does work better than the H50/A50 and H50 revision 2.

I would save your money and actually get a RASA kit. I know its not England, but look around for something similar. Real water cooling is infinitely superior to the all-in-one kits.

Hi Ive just attached the brackets looks like ram wont be a problem at worst I may have to hack off the first high bits of the ram cooler thinngy. But wow with a doulbe rad up there two fans blowing up thru the rad to the top two 200mm fans that are blowing out, that should give me the couple of degrees I need, and then I can fit a 200mm in the door panel and the back 120 can suck air in! HAHA brb just gonna order the cooler, bang goes the meal out with the misses tonight she can cook us some beans on toast LOL!

RagingCain -you are for sure right on that post. Its a jungle out there when you start oc,ing-lol.I only said what a did as one possibility and what has worked for me at times-but there is never a magic number with out trial and error.Like my new rig, my mind is melting with all the ocing i have been doing with it-lol.

Hope she doesnt get to grummpy-lol.

Oh, i see you mentioned the fan on the right side of the case-my new inwin dragon rider has one on that side too-right in back of the cpu, it was set to blow in-i just 2 days ago wanted to see what would happen if it sucked air out-it didnt do a thing to my cpu temps, but dropped my mb temps 3c. Just fyi.

I should realy quit playing with theses computers and use them for something:cool:

Hi, the ram has been stable at all levels on 7-8-7-24 @1700 the reason I said ram? in my first post is thats the thing I didnt increase the volts to when I jumped up from my previous stable OC. I read a review on that ram before I got it and the tester stuck at 1.4v in all the tests he did, I havent yet been anywhere near that much. I think Im going to try the CPU NBVolt slightly up as with that couple of notches up I gave it it went from not passing any tests to passing 1 hour of OCCT and 6+ hours of Prime blend, so going by that I reckon I was near the money there. OCCT dont do much to ram either does it? so may be why the failure in Prime and not OCCT. Gonna try that thanks again for the replys smile.gif

Hi Ragingcain, trouble is all that stuff costs twicwe as much here in UK, and im disabled and not too wealthy lol. I may even buy a double size rad and stick the damn Tubes and pump from my H50 on! Or get fifteen foot long tubes and house the H50 up un the cold loft, less noise, more cooling, cheepnis too! Yay....

2 other testing methods i use beside prime and occt are-linx and ibt, both have given me a quick idea on my settings if they are even close to working. I will use linx on setting on like 20 on prob size and like 20 runs-it takes about 45-55 minutes and can atleast give you a idea if it might be stable. IBT i will set on high or normal and run for 20 runs, than if it passes those 2 or occt too-i will run prime for the long haul over night.
